Cardiopulmonary, Biochemical and Haematological Effects of the Tiletamine/Zolazepam-Xylazine-Tramadol Combination to Provide Anaesthesia in Miniature Pigs

摘要

The objective of this study was to investigate the suitability of tiletamine/zolazepam-xylazine-tramadol combination for miniature pigs. Fourteen Chinese experimental miniature pigs subjected to this study received 3.5 mg tiletamine/zolazepam kg-1 bw, 1.32 mg xylazine kg-1 bw and 1.8 mg tramadol kg-1 bw intramuscularly, as a mixture of the drugs. Cardiopulmonary, biochemical and haematological parameters were recorded before drug administration and after anaesthesia. The combination of the compounds resulted in anaesthesia lasting about 87 min and a satisfactory immobilization for handling. Cardiopulmonary parameters were changed after administration, but there were within biologically acceptable limits. Biochemical and haematological values decreased after drug administration, however, they returned to the baseline at 24 h. At the doses described, tiletamine/zolazepam-xylazine-tramadol combination produced good immobilization in miniature pigs with minimal changes over time in cardiopulmonary, biochemical and haematological parameters.
